| 摘 要： | 大山脉春夏季受太阳加热和地形抬升作用易于形成对流过程。为研究这类对流特点，在沙特阿拉伯ＡＳＩＲ山区组织了一个ＳＡＣＰＥＸ实验计划。本文应用中国强风暴实验室ＭＢＧ（ＭＥＳＯ—Ｂｅｔａ＆Ｇａｍｍａ）非静力模式，选取适当模拟通道模拟了该计划中１９９０年５月３日一次对流降水过程。模拟结果揭示了大山脉气流强迫与对流环流相互作用的一些基本特点，展示了大山脉对流过程多种复杂的宏微观特征及其生消演变。包括山坡激发对流，大对流对小对流的抑制，云自然引晶效应等，并指出在这类对流系统中ＣＣＮ浓度对其降水类型的重要影响。此外，本文还进行了采取细致的雹云微物理参数化和采用简单的暖云微物理参数化的对比试验，结果表明两者模拟的动力场差别甚小，而云形态和降水发展有明显差异。上述结果总体上与该个例外场观测一致。

| Abstract: | ith certain channels of the non-hydrostatic MBG (Meso-Beta-Gamma) model of CAMS/PRC, the May 3. 1990 precipitation processes over Asir mountain was two dimensionally simulated. The results showed complicated features and mechanisms of the convection development. involving the dynamic and microphysical interactions between the clouds and orographic forcing. The distribution, evolution, sizes. top heights, updrafts and precipitation growth etc. of the modelling cumulonimbus clouds were generally consistent with field observation Of the SACPEX projects. In addition, certain sensitive experiments on microphysics were also taken. |
